srncIFfcATIoN forming part of Letters Patent No. 655,698, dated August 14, 190e; Application iiled February 9, 1898. Serial No. 669,675. (No model.)

To alt whom, it may concern):

Be it known that I, THOMAS Easrvvoon, a subject of the Queen of Great Britain, residing at Walsden, in the county of Lancaster, England, have invented certain new and useful Improvements in Spinning-Machines, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in yarn-spinning machines; and it has for its object to provide for the general efficiency and utility of this class of machines.

The invention consists in the features of construction and combination of parts hereinafter fully described and specifically claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designatedl by the same letters of reference in each of the views, and in which- Figure 1 is an end elevation of a spinningmachine constructed in accordance with this invention. Fig. 2 is a front elevation of a portion of the machine. vertical section, on an enlarged scale, of the twisting mechanism. Fig. 4 is a similar detail view of the base supporting the twistersleeve; and Fig. 5, a plan view of a portion of Fig. l, showing the cop-building mechanism upon an enlarged scale.

The invention is designed to overcome and obviate the variation of the extent to which the yarn is twisted in spinning and to furnish mechanism for giving an even andconstant twist. The invention is applicable toringframe machines, in which heretofore, as far as I am informed, the spindle is driven and the traveler dragged after it, causing a variation on the amount of twist on the yarn by reason of the varying diameter of the surface upon `which the winding takes place. Itis necessary for the traveler to lag to a certain extent, while the angle at which the yarn is held when winding on a small diameter gives an excessive strain thereto. To obviate these objections and to furnish an efficient and practical machine, I provide the construction shown in the accompanying drawings and which will now be described in de- Fig. 3 is acentral.

tail. As the general structural characteristics are the same as those in machines in general use, the general arrangement and operation will be clearly understood.

In accordance with the principle of this invention the sleeve G is positively driven,while the spindle S can be driven by a differential speed motion or allowed to lag by means of a drag.77 The main driving-shaft Ais suitably geared to the delivery rollers R, as shown, and extends inside of the framework and is provided with a toothed Wheel A and a swing C', the other end of the latter being attached to the shaft D of the roller D. The shaft D' is provided with a gear-wheel B and is driven by the main shaft by the intermediate gearing shown. The said rollers D and D/l are mounted in bearings on a rail D3, while from the ends of the rails D3 arms D2 eX- tend upwardly and support the rails Di, Vcarrying the twister-sleeves G. The particular construction comprises a collar F, secured within an opening in the rail and provided exteriorly near its ends with flanges forming ballraces, while the twister-sleeve surrounds the same and has corresponding ball-races to receive the balls, as shown. The collar F is provided with an annular iange F upon the upper portion thereof, and the flange F is detachably secured to the collar F by a screwthread, as shown in Figs. 3 and 4. The sleeve G has an exterior groove to receive the band or tape a, bymeans of which it is rotated from the rollers D. At the upper end of the lsleeve Gis an eye or guide G3, through which the yarn passes and by means of which the twist is imparted thereto.

The yarn is guided to the spindle SX or tube or bobbin, ast-he case may be, by means of the above-described framework, carrying the revolving twister-sleeve G, which has an upright reciprocatory movement derived from the lifter motion, diering from the usual lifter motion in that a rack-and-pinion gearing is employed instead of the upright poker.

The bobbins are placed in the usual reel, and the yarn passes through the deliveryrolls R, as is usual. The yarn passes from the rollers R through the eyes W, and thence to the guide-eyes G3 of the twister, which is conveniently a small hooked piece of metal, as shown. The rail D3 is provided with de- H", and the latter receives its motion from,

pending gear-racks R R', that intermesh with the gear-segments II H' upon the rockshaft the mechanism of the lifter or builder. This latter mechanism I preferably construct as follows: A lever-arm L is pivotally mounted at one end on the stud L', secured to the frame of the machine at the end thereof. The lever L is so mounted as to be capable of vertical oscillation. At a point near the outer end of the lever L, in the upper portion thereof, is mounted a roller L2, and above the roller L2 is mounted a shaft M', which bears a cam M, and the shaft M' is operatively connected With the main shaft A in any suitable manner and is revolved thereby at a predetermined speed, and the cam M operates in connection with the roller L2 to intermittently depress the lever L. Mountedl upon the lever L, at the outer end thereof, is a frame N, (best shown in Fig. 5,) and journaled in said frame N, transversely thereof, as at O', is a shaft O, and the shaft O bears within said frame aiixed worm J' and exteriorly of said frame a fixed ratchet-wheel K'. A pawl-arm K2 is provided out of its central point of gravity with a collar K4, by which it is mounted pivotally upon the shaft O, exteriorly of the frame N, and the frame N is provided with a lu g or stop N', under which the shorter and inner end portion K5 of the pawl-arm K3 normally rests. A pawl K2 is pivotally connected with the longer and outer end portion K6 of the paWl-arm K3 and is adapted to operatein connection with the ratchet-wheel K'.

A stop RX is secured to the frame of the machine beneath the outer end K6 of the pawlarm K2, and said'outer end K(i is adapted to come in contact with said stop RX whenthe lever Land frame N are depressed by the cam M.

A shaft S is journaled iu the frame N, as at S S', longitudinally thereof, and is provided With a gear-wheel K7, correspondingly threaded to the worm J' and in mesh therewith. The shaft S also bears a pulley J, keyed thereto. Parallelly and similarly mounted to they shaft S is another shaft T, which bears a bevel-gear T', keyed thereto, and the inner end, of the shaft 0l is provided with a corresponding fixed bevel-gear O2, which operates in connection with the bevel-gear T'. The shaft T extends eXteriorly of the fra-me N and is squared, as at T2, to receive a crank.

A chain I is secured to the chain-pulley J and extends upwardly and is secured to a chain-pulley I, revolubly mounted upon a short shaft l2, secured to the frame of the machine. Another similar chain-pulley I2is revolubly mounted upon the outer end of the shaft I2. and is locked tothe pulley I in any suitablemanner, asby a sleeve I4. Connected with thepulley l3 is a chain H3, and the chain H2 is secured at the other end to the lever H2 of thegearsegment Il', as previously described.

The operationof this portion of my im- Ls ceases provement will be readily understood. The cam M when revolved dcpresses the lever L and the frame N, bringing the end portion K6 of the pawl-arm K3 into contact with the stop RX, and as the lever L continues to de* scend the said end portion KG will be held stationary, thus in eifect revolving the pawlarm K2 about the shaft O, and the pawl K2 will force around the ratchet-Wheel K', revolving the shaft O, the Worm J', the gearwheel K7, the chain-pulley J, and drawing down the chain I', revolving the chain-pulleys I and I3 and winding up the chain H3 upon the chain-pulley I3, thus revolving the shaft H" and operating the gears H H' to raise the gear-racks R and R' and the rail D3. `The gearing of the rail D3and connections will reversely operate the lever L and connections to such an extent as allowed by the conformation of the cam M; but as at each depression of the lever L an added portion of the chain l' is Wound upon the chain-pulley J the rail D2 is intermittently raised throughout the play of the gear-racks R. When it is desired to lower the rail D2, a crank may be applied to the end T2 of the shaft T, the pawl K2 removed from the ratchet-Wheel K', and the shaft O allowed to revolve, so as to unwind the chain I' from the chain-pulley J. The said twister-sleeve is provided at itslower end with a groove or slot G' to receive a brake G2, whereby the movement of the twister may be arrested, for instance, when necessary to piece a broken end.

'The chief advantages which are claimed for this machine are that there is a constant number of turns in the yarn and also that soft-twisted yarn, such as Wofts, can be efiiciently spun.

Having fully described my invention, I claim as new and desire to secure by Letters Patent- 1.
